IMPROVEMENT IN EXTINGUISHER AND REGULATOR FOR LAMPS.

Specification forming part of Letters Patent N 0. 56,770, dated July 31, 1866.

- a full, clear, and exact description thereof,

which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 represents a transverse section of this invention when the same is open. Fig. 2 is a rear elevation of the same when closed.

Similar letters of reference indicate like parts.

This invention relates to a combined extinguisher and regulator which is composed of an adjustable sleeve fitted over the wicktube, in combination with a hinged cap,-in such a manner that when the sleeve is. depressed the cap turns back or opens and the flame is free to burn, but when the sleeve is raised to the proper point the cap closes down and the flame is extinguished. The sleeve and cap are connected to a cam-motion in such a manner that the sleeve is free to move nearly up to its highest point before the cap closes down, and by these means the flame can be regulated at pleasure or extinguished at any moment and Without danger of an explosion or of allowing a bad odor to escape in the room.

A represents a lamp-burner of the ordinary construction. On the upper part of the wickthis tail-piece extends ahook, c, which is provided with a shoulder, d, below the tail-piece, as shown, and which is connected to the sleeve 0.

When the sleeve is depressed the point of the hook bears on the upper surface of the tailpiece andthe capis turned back, leaving the wick-tube open and the flame free to burn. By raising the sleeve the flame is regulated, and when the sleeve has been raised nearly to its highest point the shoulder cl of the hook bears against the under surface of the tailpiece, and the cap is caused to close down.

By these means the flame of a lamp can not onlybe regulated at pleasure, but it can also be extinguished at any moment simply by turning the cam-shaft far enough to cause the cap to close down. All danger of an explosion is thus avoided, and the bad odor generally emanating from a kerosene or other lamp when the wick is turned down is prevented from escaping in the room.

What I claim as new, and desire to secure by Letters Patent, is

1. A lamp-burner provided with a combined regulator and extinguisher, substantially such as herein described, as a new article of manufacture.

2. The sleeve 0, adapted to act separately as a regulator, and, in combination with the cap E, as an extinguisher.

3. The cam-shaft D and hook c, with its shoulder d, in combination with the sleeve 0, wick-tube B, and cap E, constructed and operating substantially as and for the purpose described.

The above specification of my invention signed by me this 15th day of May, 1866.
